Abstract

The present invention relates to a vibration reduction device for a clothing processing device and the clothing processing device. The present invention aims to solve the problem that the vibration reduction effect of the plunger-type friction vibration reducer installed in the existing drum washing machine is poor. To this end, the present invention proposes that a sliding track arranged on the outer drum is slidably connected to a counterweight block on the side facing away from the outer drum, and the opposite ends of the counterweight block are respectively connected to a fixed bracket arranged on the outer drum through at least one tension rope. Therefore, during the operation of the clothing processing device, the vibration energy generated when the inner drum rotates will be transmitted to the counterweight block through the outer drum, and the counterweight block will slide relative to the sliding track, and the friction between the counterweight block and the sliding track can consume the vibration energy generated by the clothing processing device. At the same time, because the elongation and tension of the tension rope when hindering the sliding of the counterweight block are nonlinear, the range of vibration frequency absorption is relatively wide, thereby greatly improving the vibration absorption capacity of the vibration reduction device for the clothing processing device.

[0002] When a drum washing machine is in use, the outer drum vibrates, which reduces the life of electrical components or rubber components connected to the outer drum, and the overall vibration of the drum washing machine also affects the user experience. In order to reduce the vibration of the drum washing machine when in use, a vibration absorber is usually provided in the drum washing machine.

[0003] At present, most of the drum washing machines use plunger-type friction dampers, which include a friction ring and a damping cylinder. One of the friction ring and the damping cylinder is fixed to the drum washing machine body, and the other is fixed to the outer drum. When the outer drum vibrates, the mutual friction between the friction ring and the damping cylinder reduces the vibration of the outer drum.

[0004] However, the vibration reduction method of the above-mentioned plunger-type friction shock absorber is friction damping type, which consumes vibration energy by utilizing the mutual friction between the friction ring and the damping cylinder when the outer cylinder vibrates. Its vibration reduction effect must be based on the vibration of the outer cylinder, that is, part of the vibration energy is consumed during the vibration of the outer cylinder, so its vibration reduction effect is limited.

[0010] As a preferred technical solution of the vibration reduction device provided by the present invention, heat dissipation holes corresponding to the contact surface are formed on the fixing bracket.

[0011] As a preferred technical solution of the above-mentioned vibration reduction device provided by the present invention, the sliding track is a linear track, and the extension direction of the linear track is parallel to the tangent of the rotation direction of the inner cylinder; or, the sliding track is an arc track, and the extension direction of the arc track is a circle coaxial with the rotation direction of the inner cylinder.

[0012] As a preferred technical solution of the above-mentioned vibration reduction device provided by the present invention, a T-shaped slot is provided on the counterweight block, and a T-shaped sliding portion that is slidably adapted to the T-shaped slot is formed on the sliding track; and / or, the fixed bracket is a U-shaped bracket, and both ends of the U-shaped bracket are fixedly connected to the outer cylinder.

[0013] As a preferred technical solution of the above-mentioned vibration reduction device provided by the present invention, the tensioning rope extends parallel to the axis of the inner cylinder; or the tensioning rope extends along a direction parallel to a tangent of the inner cylinder; and / or, a tensioning rope is connected to the middle of one end of the counterweight block; or two tensioning ropes are connected to one end of the counterweight block, and the two tensioning ropes are symmetrically arranged relative to the center line of the one end.

[0014] As a preferred technical solution of the above-mentioned vibration reduction device provided by the present invention, the tensioning rope is a steel wire rope or a nylon rope.

[0015] In addition, the present invention also provides a clothes processing device, which includes a box body, an outer drum fixedly connected to the box body, an inner drum rotatably arranged in the outer drum, and any one of the above-mentioned vibration reduction devices.

[0025] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

Without departing from the principles of the present invention, those skilled in the art can apply the vibration reduction device of the present invention to other clothing processing devices, such as pulsator washing machines, shoe washing machines, etc.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the vibration reduction effect of the above-mentioned plunger type friction damper installed in the existing drum washing machine must be based on the vibration of the outer drum, that is, part of the vibration energy is consumed during the vibration of the outer drum, so its vibration reduction effect is limited, the present embodiment provides a vibration reduction device for a clothing processing device and a clothing processing device.

[0029] like Figures 1 to 3As shown, first, this embodiment provides a vibration reduction device 1 for a clothing processing device, wherein the clothing processing device includes a housing 3, an outer cylinder 2 fixedly connected to the housing 3, and an inner cylinder (not shown in the figure) rotatably arranged in the outer cylinder 2, and the vibration reduction device 1 includes a sliding track 11, a counterweight 12, a tensioning rope 13 and a fixed bracket 14; the tensioning rope 13 is a non-linear elastic rope; the sliding track 11 and the fixed bracket 14 are both arranged on the outer cylinder 2; the side of the sliding track 11 facing away from the outer cylinder 2 is slidably connected to the counterweight 12, and the opposite ends of the counterweight 12 are respectively connected to the fixed bracket 14 by at least one tensioning rope 13, and the tensioning rope 13 is arranged so that when the counterweight 12 slides along the track, at least one end of the tensioning rope 13 prevents the counterweight 12 from sliding.

[0030] Exemplarily, the sliding track 11 can be a straight track or an arc track. When the sliding track 11 is a straight track, the extension direction of the straight track is parallel to the tangent of the rotation direction of the inner cylinder. Figures 1 to 3 The straight track shown in the figure is such a setting mode; when the sliding track 11 is an arc track, the extension direction of the arc track is a circle coaxial with the rotation direction of the inner drum. Therefore, when the counterweight block 12 slides along the sliding track 11, the sliding direction of the counterweight block 12 just matches the vibration direction of the outer drum 2, so as to ensure the vibration absorption effect of the vibration reduction device 1 on the clothing processing equipment.

[0031] The counterweight 12 can be a heavy device such as a steel block, an iron block, a zinc block, or a lead block. When the outer cylinder 2 vibrates, it can slide relative to the sliding track 11 or slide a small amount. This embodiment also shows a sliding connection method between the counterweight 12 and the sliding track 11, such as Figure 2 and Figure 3 As shown, a T-shaped slot is provided on the counterweight 12, and a T-shaped sliding portion adapted to slide with the T-shaped slot is formed on the sliding track 11. The sliding track 11 mainly limits the counterweight 12, so that the counterweight 12 can only move along the extension direction of the sliding track 11.

[0032] The tension rope 13 is required to be a non-linear elastic rope, that is, its tension is not proportional to the elongation. For example, the tension may be proportional to the cube of the elongation. The tension rope 13 may be a steel wire rope or a nylon rope, or other types of non-linear elastic ropes.

[0033] The fixing bracket 14 may be a U-shaped bracket, both ends of which are fixedly connected to the outer cylinder 2, and the fixing bracket 14 mainly serves to fix the other end of the tension rope 13. Furthermore, the fixing bracket 14 may also be formed with a contact surface against the counterweight 12, so that the vibration energy generated by the clothes processing device can be consumed through the friction between the counterweight 12 and the fixing bracket 14 during the sliding process of the counterweight 12.

[0034] Taking a drum washing machine as an example, when the tensioning rope 13 connects the fixing bracket 14 and the counterweight 12, the tensioning rope 13 can extend parallel to the axis of the inner drum, that is, the sliding direction of the tensioning rope 13 and the counterweight 12 is perpendicular. Figures 1 to 3 The tensioning rope 13 in the inner tube is set in this way; alternatively, the tensioning rope 13 can extend in a direction parallel to a tangent line of the inner tube, that is, the tensioning rope 13 is set along the sliding direction of the counterweight 12.

[0035] In order to ensure that the counterweight 12 is evenly stressed when the tensioning rope 13 is tensioning the counterweight 12, a tensioning rope 13 may be connected to the middle of one end of the counterweight 12; or, two tensioning ropes 13 may be connected to one end of the counterweight 12, and the two tensioning ropes 13 are symmetrically arranged relative to the center line of one end.

[0036] In a vibration reduction device 1 for a clothing processing device provided in this embodiment, a sliding track 11 disposed on an outer drum 2 is slidably connected to a counterweight 12 on the side facing away from the outer drum 2, and opposite ends of the counterweight 12 are respectively connected to a fixed bracket 14 disposed on the outer drum 2 through at least one tension rope 13. Thus, during the operation of the clothing processing device, the vibration energy generated by the rotation of the inner drum will be transmitted to the counterweight 12 through the outer drum 2, or it can be considered that the counterweight 12 absorbs the vibration energy, and the counterweight 12 will slide relative to the sliding track 11, and the friction between the counterweight 12 and the sliding track 11 can consume the vibration energy generated by the clothing processing device. At the same time, the tension rope 13 at one end of the counterweight 12 will be slightly elongated and generate a force that hinders the sliding of the counterweight 12. Since the tension rope 13 is a nonlinear elastic rope, its elongation and tension are nonlinear, and its range of vibration frequency absorption is relatively wide, thereby greatly improving the vibration absorption capacity of the vibration reduction device 1 for the clothing processing device.

[0037] As a preferred implementation of the above-mentioned vibration reduction device 1 provided in this embodiment, the fixed bracket 14 is formed with a contact surface that abuts against the counterweight block 12, and the extension direction of the contact surface is adapted to the sliding track 11 of the counterweight block 12 so that the counterweight block 12 can always be in contact with the contact surface when sliding.

[0038] The counterweight 12 may directly abut against the contact surface of the fixed bracket 14, or indirectly abut against the contact surface of the fixed bracket 14. For example, a friction damping plate 15 may be directly provided between the counterweight 12 and the contact surface. Therefore, the vibration reduction device 1 may further include a friction damping plate 15, and the specific arrangement of the friction damping plate 15 may be that one side of the friction damping plate 15 is fixedly connected to the side of the counterweight 12 facing the contact surface, and the other side of the friction damping plate 15 abuts against the contact surface; the specific arrangement of the friction damping plate 15 may also be that one side of the friction damping plate 15 is fixedly connected to the contact surface, and the other side of the friction damping plate 15 abuts against the side of the counterweight 12 facing the contact surface.

[0039] In order to avoid the high temperature generated by repeated friction between the counterweight 12 and the contact surface of the fixed bracket 14 when the counterweight 12 directly contacts and rubs with the contact surface or contacts and rubs through the friction damping plate 15, so as to prevent the deformation of the opposite surfaces of the counterweight 12 and the friction, which will have an adverse effect on the friction, a heat dissipation hole 141 corresponding to the contact surface can be provided on the fixed bracket 14 to avoid heat accumulation. The heat dissipation hole 141 can be a through hole extending outward from the contact surface of the fixed bracket 14.

[0040] In the vibration reduction device 1 provided in this embodiment, a friction damping plate 15 is further arranged between the contact surface of the counterweight block 12 and the fixed bracket 14. Through the friction between the counterweight block 12 and the fixed bracket 14, the vibration energy generated by the clothing processing equipment is further consumed, thereby further improving the vibration absorption capacity of the vibration reduction device 1 for the clothing processing equipment.

[0041] In addition, this embodiment also provides a clothes processing device, which includes a box body 3, an outer drum 2 fixedly connected to the box body 3, an inner drum rotatably arranged in the outer drum 2, and any of the above-mentioned vibration reduction devices 1. Taking a drum washing machine as an example, the sliding track 11 can be arranged on the upper side of the outer drum 2 in the horizontal direction, such as Figures 1 to 3 This is the arrangement mode; and / or, the sliding track 11 is respectively arranged on the left and right sides of the outer cylinder 2 in the vertical direction. That is, the sliding track 11 can be arranged on the upper side of the outer cylinder 2 in the horizontal direction, or on the left and right sides of the outer cylinder 2 in the vertical direction, or the vibration reduction device 1 can be arranged on the upper side and both the left and right sides of the outer cylinder 2. In essence, the extending direction of the sliding track 11 is parallel to the tangent of the rotation direction of the inner cylinder.

[0042] In the above-mentioned clothes processing device provided in this embodiment, since the above-mentioned vibration reduction device 1 is installed in the clothes processing device. Therefore, when the vibration generated by the rotation of the inner drum of the clothes processing device is transmitted to the outer drum 2 during operation, the counterweight block 12 will slide relative to the sliding track 11, and the friction between the counterweight block 12 and the sliding track 11 can consume the vibration energy generated by the clothes processing device. At the same time, the tension rope 13 at one end of the counterweight block 12 will be slightly elongated and generate a force that hinders the sliding of the counterweight block 12. Since the tension rope 13 is a non-linear elastic rope, its elongation and tension are nonlinear, and its range of vibration frequency absorption is relatively wide, thereby greatly improving the vibration absorption capacity of the vibration reduction device 1 on the clothes processing device.

[0043] In addition, those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of protection of the present invention and to form different embodiments. For example, in the claims of the present invention, any one of the claimed embodiments may be used in any combination.

[0044] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
